What is temperature?


AA measure of the melting point characteristic of a substance
BA measure of the average pressure acting on a substance
CA measure of the average forces within a substance
DA measure of the average kinetic energy of a substance

Verified Answer :

Final answer:

Temperature is a measure of the average kinetic energy of particles in a substance. As temperature increases, particle movement increases, leading to higher kinetic energy. The correct answer is Option D.


Explanation:

What is Temperature?

Temperature is defined as a measure of the average kinetic energy of the particles in a substance. This means that as the temperature of a substance increases, the particles move more rapidly, leading to a higher average kinetic energy. For example, when water is heated, the molecules vibrate and move faster, which is why the water becomes hotter.

In contrast, the options provided in the question can be clarified as follows:

  • Option A, which describes the melting point, refers specifically to the temperature at which a solid becomes a liquid, rather than a general measure of temperature.
  • Option B mentions average pressure, which is unrelated to temperature.
  • Option C discusses average forces, but temperature specifically references kinetic energy rather than all forces acting within a substance.

Thus, the correct answer to the question is Option D: a measure of the average kinetic energy of a substance.
